A system includes a hybrid fiber-coaxial network which carries content signals between a service provider system and premises, where the hybrid fiber-coaxial network is susceptible to receiving wireless noise signals, a plurality of passive noise dampeners, each passive noise dampener connected between the hybrid fiber-coaxial network and a premise of the premises. Each passive noise dampener includes an antenna based on medium used in the hybrid fiber-coaxial network. The antenna receives the wireless noise signals. A phase shifting device phase shifts 180 degrees phase shift the wireless noise signals received by the antenna to generate a counter signal. A directional coupler injects the counter signal into the hybrid fiber-coaxial network to mitigate impact of the wireless noise signals received by the hybrid fiber-coaxial network on the content signals. The antenna, the phase shifting device, and the directional coupler are passive devices."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Passive noise dampeners","description":"Methods and systems for a passive noise dampener.
